This adapter kit allows you to bolt the Toyota RF1A Gear Drive Transfer case behind your Tacoma/4Runner/T100 5-speed or automatic transmission.

We have designed our kit using a 23-spline coupler for ultimate strength. Therefore, a 23-spline gear drive transfer case or Crawl Box input will be required.

Also, this short 1/2"-thick design requires a top-shift style transfer case or Crawl Box.

Please note: This kit requires a 23-spline gear drive t/case input gear. Please click the image to the left to view our Total-Spline 23-spline input gear.
